Title: Semiconductor device
Inventor: TANAKA MASATO
IPC: H01L21/762
Filed: 1987-04-16
Abstract: PURPOSE:To enable the composition of this semiconductor device which is completely isolated both lengthwise and widthwise from a substrate and does not require an epitaxial layer, by equipping an element isolation region which is formed at a connection part between two crystal planes and the substrate and is made of a substrate oxidizing film. CONSTITUTION:After a silicon oxide film 14 and a silicon nitride film 15 are formed over the whole surface of a silicon substrate 11, a posi-resist 16 is used to perform selective etching of a bottom part on a <110> crystal plane of projected silicon 13. In succession, selective oxidation of the <110> silicon crystal plane is performed until it attains to a <-1-10> crystal plane on a back side of the substrate 11, so that an element isolation region 17 is formed to perform dielectric isolation of the projected silicon 13 from the silicon substrate 11. An element which is completely dielectrically isolated both lengthwise and widthwise from the substrate is thus formed on the crystal plane dissimilar to the substrate plane in this semiconductor device. Accordingly this device does not require an epitaxial layer of conventional structure or the like at all and is equipped with the element region which is completely isolated from the substrate, so that a bipolar transistor which is made very high-speed can be composed.

Abstract: PURPOSE:To ensure a high accuracy in measuring a hot water level in a bathtub filled with hot water by a method wherein the detection of the hot water level is made only when an output value from a hot water level sensor with respect to time varies in a range of 0 to 20cm/min in term of a hot water level in the bathtub or a hot water level rising speed in the bathtub at the time of the detection of output variations corresponding to the submergency of a bath adaptor. CONSTITUTION:In a case where a hot water stream switch 16 connected to the outlet port 15 of a pump 13 is kept ON continuously for a fixed period of time, hot water is judged to be in a residual state, and whether the hot water level in a bathtub is higher than a preset hot water level is judged. In a case where it is higher than the preset hot water level, additional heating and temperature holding operations are carried out. In a case where no residual state of water is judged, a shut-off valve 24 is opened to feed hot water into the bathtub 19 for a predetermined period of time through pipelines 18, 23, and thereafter, the shut-off valve 24 is closed to feed hot water into the bathtub 19 through the pipeline 18. According to this hot water feed method, when an output value from a hot water sensor 22 provided on a pipeline 21 becomes DELTAv0 in a range of 0 to 20cm/min, a three-way change- over valve 12 is operated to form a circulation passage for additional heating, and supplied hot water is circulated.

Thus the circuit 8 works to supply the 2nd control signal e2 obtained at an output terminal 7b of a voltage relay 7 to a line voltage controller 2. Accordingly the controller 2 performs a control immediately in case when the circuit 1B has a sudden fluctuation of load to cope with a sudden fluctuation of voltage.
